What is Potato Dauphinoise?

It’s a French dish often made up of sliced potatoes baked in milk. Traditionally named ‘Gratin Dauphinois’, this dish has taken on a number of different names and a few different tweaks in ingredients too. Here’s what I like in mine:

Potato Dauphinoise Ingredients

Milk

Cream

Nutmeg

Garlic

Butter

Gruyere (to top)

Yup, pretty simple right? It’s one of those recipes that requires such few ingredients but tastes so incredible.

I feel that a 50/50 ratio of milk and cream gives the perfect amount of richness. I also love grilling some gruyere on top at the very end because, erm, just look at that golden crispy goodness!

When it comes to making potato dauphinoise it truly couldn’t be more simple.

How to make Potato Dauphinoise

Slice your potatoes to around 1/8″ thickness.

Simmer milk and cream with nutmeg, a crushed clove of garlic and salt & pepper.

Mix in potato slices to fully coat.

Rub a baking dish with butter and garlic, then add your potatoes.

Bake for 1 hour 15mins.

Top with gruyere and grill until golden and crispy.

Simple right?

Tips for the best Potato Dauphinoise

Make sure all over your slices are the same thickness so they cook at an even rate.

Work in layers of potato and sauce to ensure a full coverage of cream on the potatoes.

Ensure you use double/heavy cream and cook at a low temperature to ensure the cream doesn’t curdle.

Begin by slicing your potatoes into very thin rounds (approx 3-4mm or 1/8").

In a pot, add your milk, cream, nutmeg, 1 clove of garlic, salt & pepper and bring to a gentle simmer. Allow to infuse for 5 mins then take out your garlic. Stir in your potatoes, ensuring they're fully coated.

Grab an oven proof dish and rub with garlic then do the same with a knob of butter. Stack in layers of potato and sauce to ensure the potatoes get the most sauce coverage as possible. Finish with a thin layer of sauce.

Pop in the oven at 160c/320f for 1 hour and 15mins or until knife tender and browned on the top. Take out and cover with a layer of gruyere then pop under the grill until golden and bubbly.

Serve with a sprinkling of fresh chives!
